This question tests CCSS.L.6.1.a: using proper pronoun case (subjective, objective, possessive) based on grammatical function in the sentence. Pronoun case refers to the form a pronoun takes based on its role in a sentence. Subjective case (I, he, she, we, they) is used for subjects and predicate nominatives; objective case (me, him, her, us, them) is used for direct objects, indirect objects, and objects of prepositions; possessive case (my/mine, his, her/hers, our/ours, their/theirs) shows ownership. In this sentence, the pronoun follows the preposition 'to' and serves as the object of that preposition. This requires objective case because pronouns that follow prepositions must always be in objective case. Choice D 'them' is correct because it is the objective case form of 'they', which matches its function as the object of the preposition 'to'. The sentence means the trophy was given to them (a group of people). Choice A 'they' represents a common error where students use subjective case after prepositions, not recognizing that prepositions always take objective case. This error often occurs because students focus on the pronoun's meaning (referring to people who won) rather than its grammatical function (object of preposition). To help students identify correct case: (1) After ANY preposition (to, from, with, for, between, etc.), ALWAYS use objective case. (2) Common prepositions to watch for: to, from, with, for, at, by, in, on, between, among, beside, beneath. (3) The subject-object pairs are: I/me, he/him, she/her, we/us, they/them. (4) Test by substituting a pronoun you're sure about: 'went to him' not 'went to he'. (5) Don't be confused by meaning - even though 'they' won the tournament, after 'to' you need 'them'.

Pronoun case refers to the form a pronoun takes based on its role in a sentence. Subjective case (I, he, she, we, they) is used for subjects and predicate nominatives; objective case (me, him, her, us, them) is used for direct objects, indirect objects, and objects of prepositions; possessive case (my/mine, his, her/hers, our/ours, their/theirs) shows ownership. In this sentence, the pronoun follows the linking verb 'is' and functions as a predicate nominative that renames the subject 'The missing Chromebook charger'. This requires the possessive pronoun 'mine' (not 'my') because it stands alone without a noun following it. Choice C 'mine' is correct because it is the independent possessive pronoun that can stand alone after a linking verb to show ownership. The sentence means the charger belongs to me, not to Carlos. Choice A 'my' represents a common error where students confuse the two forms of possessive pronouns - 'my' must be followed by a noun (my charger), while 'mine' stands alone (the charger is mine). This error often occurs because students know they need to show possession but don't distinguish between attributive possessives (my, your, his, her, our, their) and independent possessives (mine, yours, his, hers, ours, theirs). To help students identify correct case: (1) Possessive pronouns have two forms - one that goes before nouns (my book) and one that stands alone (the book is mine). (2) After linking verbs (is, are, was, were), use independent possessives: mine, yours, his, hers, ours, theirs. (3) The pattern is: 'The [noun] is mine' NOT 'The [noun] is my'. (4) Remember: his and its are the same in both forms. (5) Common errors include using 'my' after 'is' or using 'mines' (which isn't a word).

Pronoun case refers to the form a pronoun takes based on its role in a sentence. Subjective case (I, he, she, we, they) is used for subjects and predicate nominatives; objective case (me, him, her, us, them) is used for direct objects, indirect objects, and objects of prepositions; possessive case (my/mine, his, her/hers, our/ours, their/theirs) shows ownership. In this sentence, the pronoun follows the preposition 'to' and is part of the compound object 'Jamal and ___'. This requires objective case because pronouns that follow prepositions must be in objective case. Choice B 'me' is correct because it is the objective case form, which matches its function as the object of the preposition 'to'. The sentence means Marcus handed the notes to two people: Jamal and me. Choice A 'I' represents a common hypercorrection error, where students use subjective case thinking it sounds more formal or proper, but this is incorrect after a preposition. This error often occurs when students have been corrected for using 'me' incorrectly as a subject and then overcorrect by avoiding 'me' entirely. To help students identify correct case: (1) Find the pronoun's function - is it doing the action (subject/subjective), receiving the action (object/objective), or showing ownership (possessive)? (2) In compound constructions ('Jamal and me'), remove the other person temporarily to test which sounds right ('handed the notes to me' vs 'handed the notes to I'). (3) After prepositions (to, for, with, between, etc.), always use objective case (to me, for her, with him, between us).

Subjective case (I, he, she, we, they) is used for subjects and predicate nominatives; objective case (me, him, her, us, them) is used for direct objects, indirect objects, and objects of prepositions; possessive case (my/mine, his, her/hers, our/ours, their/theirs) shows ownership. In this sentence, the pronoun is part of the compound subject '___ and Sofia' that performs the action 'worked'. This requires subjective case because the pronoun is functioning as the subject of the sentence. Choice C 'I' is correct because it is in subjective case, which matches its function as part of the compound subject performing the action. The sentence means two people (I and Sofia) worked together on the poster. Choice A 'Me' represents a common error where students use objective case for subjects, often because they're unsure about case in compound constructions. This error often occurs when students default to 'me' because it sounds less formal or when they've heard phrases like 'Me and my friend' in casual speech. To help students identify correct case: (1) Find the pronoun's function - is it doing the action (subject/subjective), receiving the action (object/objective), or showing ownership (possessive)? (2) In compound constructions ('I and Sofia' or 'me and Sofia'), remove the other person temporarily to test which sounds right ('I worked' vs 'Me worked'). (3) Remember that subjects always use subjective case, even in compound constructions. (4) The position at the beginning of a sentence doesn't automatically mean 'I' - it depends on grammatical function.

Pronoun case refers to the form a pronoun takes based on its role in a sentence. Subjective case (I, he, she, we, they) is used for subjects and predicate nominatives; objective case (me, him, her, us, them) is used for direct objects, indirect objects, and objects of prepositions; possessive case (my/mine, his, her/hers, our/ours, their/theirs) shows ownership. In this sentence, the pronoun is the subject performing the action 'volunteered'. This requires subjective case because the pronoun is functioning as the subject of the sentence - it's doing the action. Choice C 'He' is correct because it is in subjective case, which matches its function as the subject performing the action of volunteering. The sentence means he volunteered at the library, and Maya also helped. Choice A 'Him' represents a common error where students use objective case at the beginning of a sentence, possibly because they're unsure about case or because they've heard objective pronouns used incorrectly as subjects in casual speech. This error often occurs when students think position in the sentence determines case rather than grammatical function. To help students identify correct case: (1) Find the pronoun's function - is it doing the action (subject/subjective), receiving the action (object/objective), or showing ownership (possessive)? (2) Subjects always use subjective case, regardless of where they appear in the sentence. (3) Test by asking 'Who volunteered?' - the answer 'He' shows it's the subject. (4) Beginning of sentence doesn't automatically mean subjective case, but subjects often appear there. (5) Remember: pronouns at the start of sentences are usually (but not always) subjects - verify by finding what action they perform.

This question tests CCSS.L.6.1.a: using proper pronoun case (subjective, objective, possessive) based on grammatical function in the sentence. Pronoun case refers to the form a pronoun takes based on its role in a sentence. Subjective case (I, he, she, we, they) is used for subjects and predicate nominatives; objective case (me, him, her, us, them) is used for direct objects, indirect objects, and objects of prepositions; possessive case (my/mine, his, her/hers, our/ours, their/theirs) shows ownership. In this sentence, the pronoun is part of the compound direct object 'Chen and ___' that receives the action 'chose'. This requires objective case because the pronoun is functioning as a direct object - it's receiving the action of the verb. Choice B 'her' is correct because it is in objective case, which matches its function as part of the compound direct object. The sentence means the teacher chose two people: Chen and her. Choice A 'she' represents a common error where students use subjective case for objects, often because they think it sounds more proper or formal. This error often occurs in compound constructions where students lose track of the pronoun's grammatical function. To help students identify correct case: (1) Find the pronoun's function - is it doing the action (subject/subjective), receiving the action (object/objective), or showing ownership (possessive)? (2) In compound constructions ('Chen and her'), remove the other person temporarily to test which sounds right ('The teacher chose her' vs 'The teacher chose she'). (3) Direct objects always use objective case - ask 'chose whom?' to identify the direct object. (4) Don't be fooled by word order - even though the pronoun comes after 'and', it's still receiving the action of 'chose'.

In this sentence, the pronoun is part of the compound direct object 'Keisha and ___' that receives the action 'congratulated'. This requires objective case because the pronoun is functioning as a direct object - it's receiving the action of the verb. Choice B 'us' is correct because it is the objective case form of 'we', which matches its function as part of the compound direct object. The sentence means the coach congratulated two parties: Keisha and us (our group/team). Choice A 'we' represents a common error where students use subjective case for objects, often in compound constructions where they lose track of grammatical function. This error often occurs because students think 'we' sounds more proper than 'us', similar to the 'I/me' confusion. To help students identify correct case: (1) Find the pronoun's function - is it doing the action (subject/subjective), receiving the action (object/objective), or showing ownership (possessive)? (2) In compound constructions ('Keisha and us'), remove the other person temporarily to test which sounds right ('The coach congratulated us' vs 'The coach congratulated we'). (3) Direct objects always use objective case - ask 'congratulated whom?' to identify the direct object. (4) Remember the subject/object pairs: I/me, he/him, she/her, we/us, they/them. (5) Don't let compound constructions confuse you - the case depends on function, not position.

Subjective case (I, he, she, we, they) is used for subjects and predicate nominatives; objective case (me, him, her, us, them) is used for direct objects, indirect objects, and objects of prepositions; possessive case (my/mine, his, her/hers, our/ours, their/theirs) shows ownership. In this sentence, the pronoun follows the preposition 'between' and is part of the compound object 'you and ___'. This requires objective case because pronouns that follow prepositions must always be in objective case. Choice B 'me' is correct because it is the objective case form, which matches its function as the object of the preposition 'between'. The phrase means 'between two people: you and me'. Choice A 'I' represents the classic hypercorrection error 'between you and I', where students use subjective case thinking it sounds more educated or formal, but this is grammatically incorrect. This error is so common it has become a linguistic phenomenon - people avoid 'me' because they've been corrected for using it incorrectly as a subject ('Me and John went' should be 'John and I went'), then overcorrect by never using 'me' at all. To help students identify correct case: (1) After ANY preposition (between, to, for, with, from, etc.), ALWAYS use objective case. (2) The phrase 'between you and I' is NEVER correct - it's always 'between you and me'. (3) Test by removing the other person: 'between me' not 'between I'. (4) Don't let formality fool you - grammatically correct isn't always what sounds fancy. (5) Common preposition errors include: between you and I, for John and I, with Sarah and I - all should use 'me'.

This question tests CCSS.L.6.1.a: using proper pronoun case (subjective, objective, possessive) based on grammatical function in the sentence. Pronoun case refers to the form a pronoun takes based on its role in a sentence. Subjective case (I, he, she, we, they) is used for subjects and predicate nominatives; objective case (me, him, her, us, them) is used for direct objects, indirect objects, and objects of prepositions; possessive case (my/mine, his, her/hers, our/ours, their/theirs) shows ownership. In this sentence, the pronoun modifies the gerund 'sketching' (an -ing word functioning as a noun), showing whose sketching is being praised. This requires possessive case because pronouns before gerunds must be possessive to show whose action is being discussed. Choice C 'his' is correct because it is the possessive case form, which is required before the gerund 'sketching'. The sentence means the teacher praised the sketching that belongs to him - his act of sketching. Choice A 'him' represents a common error where students use objective case before gerunds, not recognizing that gerunds require possessive pronouns. This error often occurs because the sentence might sound acceptable with 'him' in casual speech, but formal grammar requires the possessive. To help students identify correct case: (1) Before gerunds (-ing words used as nouns), always use possessive case. (2) The pattern is: possessive + gerund (his singing, her dancing, their laughing, my running). (3) Test by asking 'whose sketching?' - the answer shows you need possession. (4) Don't confuse with progressive verbs: 'I saw him sketching' (progressive verb) vs 'I praised his sketching' (gerund). (5) Common gerund errors include: 'I don't like him singing' (should be 'his singing'), 'They enjoyed us performing' (should be 'our performing'). Remember: if the -ing word is the thing being acted upon (praised, enjoyed, discussed), it's a gerund and needs possessive case before it.

This question tests CCSS.L.6.1.a: using proper pronoun case (subjective, objective, possessive) based on grammatical function in the sentence. Pronoun case refers to the form a pronoun takes based on its role in a sentence. Subjective case (I, he, she, we, they) is used for subjects and predicate nominatives; objective case (me, him, her, us, them) is used for direct objects, indirect objects, and objects of prepositions; possessive case (my/mine, his, her/hers, our/ours, their/theirs) shows ownership. In this sentence, the pronoun modifies the noun 'backpack' to show ownership or possession. This requires possessive case, specifically the attributive form that comes before a noun. Choice A 'her' is correct because it is the possessive case form that properly modifies 'backpack', showing that the backpack belongs to Yuki (a female). The sentence means this is Yuki's backpack, so please return it to her. Choice C 'hers' represents a common error where students use the independent possessive form (which stands alone) instead of the attributive form (which modifies a noun). This error occurs because students know they need possession but confuse the two forms of possessive pronouns. To help students identify correct case: (1) Before nouns, use attributive possessives: my, your, his, her, its, our, their (her backpack, my book, their house). (2) Standing alone, use independent possessives: mine, yours, his, hers, its, ours, theirs (the backpack is hers). (3) The pattern is: possessive + noun (her backpack) vs noun + is + independent possessive (the backpack is hers). (4) Never use 'hers' directly before a noun - it's always 'her + noun'. (5) Common errors include: 'hers backpack' (should be 'her backpack'), 'mines book' (should be 'my book' - 'mines' isn't a word).
